Comparing pumping test between Boulton and Neuman in unconfined aquifer

Abstract

Groundwater is known as a crucial source of water in the history of human, as it less contaminated, it has more preferable than surface water. Analyzing data of pumping test for evaluating aquifer parameters specific yield (Sy), transmissivity (T) and storativity (S) are usually using standard procedures like Theis or Jacob method. Boulton was the first to present the delayed response concept of unconfined aquifers under pumping conditions. Then Neuman used a different method than Boulton to develop an analytical model for a fully penetrating well in unconfined aquifers. The Neuman's model is depended on physical parameters which are well defined in aquifer system that is the main difference comparing to Boulton model. The main objective of this research on understanding water table aquifers in the Xabat area is to analyze the two main Boulton and Neuman methods by using aquifer test pro 2016 software and to see which of them are most appropriate for this area, which is the main reason for applying and comparing the two methods. The results of the layer property (specific yield, transmissivity, and storativity) are similar depending on the user and the availability of the methods, as well as the future development of the program analysis.
